        How does it find a circuit breaker
        ByNov 29, 2024
        1 Answer | 
        Answer This Question

        For full instructions please see the Use and Care Manual under Additional Resources From the Manufacturer. Circuit Breaker Finder (energized and de-energized) 1. Connect the Transmitter to the circuit to be identified using either the direct ground or remote ground connection and power the Transmitter on. The direct ground and remote ground connection methods can be used on both energized and de-energized circuits, but an energized circuit produces a higher signal strength. 2. Verify that the Energized Indicator on the Transmitter is illuminated if connected to a circuit with voltage above 25V AC/DC and is not illuminated for de-energized circuits. 3. Go to the electrical panel and power on the Receiver. If there is more than one panel, touch the tip of the Receiver to each panel cover to identify the panel with the highest signal level. Use the Increase Sensitivity and Decrease Sensitivity buttons to adjust the Receiver sensitivity level to identify the panel with the highest reading. 4. Once the panel has been identified, open the cover. 5. Orient the Receiver facing left or right and perpendicular to the breakers (See below). Slowly move the Receiver up and down in front of each breaker. Use the Increase Sensitivity and decrease Sensitivity buttons to adjust the Receiver sensitivity levels as needed to locate the breaker with the highest reading. After any sensitivity level changes, rescan all the breakers to find the breaker with the highest reading.

              Can this kit be used to trace DC circuits & Breakers? Seems the answer would be yes, though trying to verify. Assuming you would use tge alligator clips on supply / return wires as you would with AC?

                  Worked much better than expected. Used to trace course and locate break in an underground 220 volt line inside pvc conduit. Strong signal obtained from line origin to break approx 133 feet length 18-24 inch depth. Previously electrician ($100 service call) said only option would be to replace the line. Klein ET 450 was cheaper than most other line tracers and anbout same price as a one day rental.Home Depot had best price. Subsequently used to confirm breaker for some mystery switches that seem to have no function in my house.

                  It was easy to set up and saved tons of time to trace a fault in a circuit. Also used it to identify individual conductors.

                  If you need to track down a dead circuit, this is the tool for you
                  I've had a dead outlet on my kitchen island for years that has been driving me up the wall. Your average circuit tester requires power to the outlet to find the breaker it is attached to. This device actually sends a tone through the dead circuit to trace the wiring back to the disconnect. I found the wire had been disconnected in a junction box several feet away above a drop ceiling in the basement and the wire had been pulled back and wadded up. The tracer will work on both live and dead circuits and has a voltage notification on the tone generator. The distance that the receiver can receive the tone is quite impressive as well. I was able to hold it a foot or so from the ceiling and trace the wire with no issues. The kit comes with every adapter you could think of including alligator clips. I used the simple lamp cord style adapter but plan to use the clips to trace a phantom light switch next.

                    Good product for the money
                    I was skeptical at first. I used the one my co-worker had on had. For the price and the capabilities it definitely worth it. Was able to pin point the location of a wire that had been cut by another trade. Didn’t have to cut unnecessary holes. Will definitely be buying one!.

                      I bought this on 06/08/22 and saved me a lot. of time tracing the outlet with no hot. Traced it, learned that it had disconnected itself from the wire but.

                        The new easy Button
                        As a well experienced Facility engineer in Fairbanks, Ak bought this yesterday and was able to find wiring issues in an older building which have haunted the owners for years in a matter of minutes. I have used circuit tracers in the past, but this is so easy and simple, easy to read display and instructions. The price was well worth it by saving time. If you can't justify owning one tell your buddy the tool junky so you can borrow it!

                          I mainly purchased the ET450 to trace circuits at my house and for that it works really well. I can identify my circuits fairly easily without having to turn off circuits and hunt around for what I shut off. I have had my Klein ET450 for about a month and I like it's quality and functionality

                          My Review of the Klein Tools ET450 Advanced Circuit Tracer Kit
                          This is not something I use every day, but when I do need to trace a circuit or find a breaker, it’s reliable and gets the job done. The kit is pretty straightforward to use. I connect the transmitter to the circuit, and the receiver picks up the signal. Adjusting the sensitivity helps me zero in on the right wire or breaker. The beeps and lights on the receiver are clear, so I don’t have to guess if I’m on the right track. It’s accurate enough for my needs. I’ve traced wires through walls, drop ceiling, and conduit. It can pick out a single wire in a bundle, which is useful when things are messy. The voltage indicators on the transmitter are helpful for knowing what I’m dealing with. The carrying case is sturdy and keeps everything together. It’s not too bulky. All in all, the ET450 is a solid tool to have around. It’s easy to use, accurate, and the carrying case is a plus. If you occasionally need to trace circuits or find breakers, this kit is worth considering.
